Pentaboron sodium octaoxide

Explosiveness

Administrative data

Endpoint:

explosive properties of explosives

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties

Justification for type of information:

According to Annex VII, section 7.11, column 2 of Regulation No. 1907/2006, explosive properties of the substance are not required if there are no chemical groups associated with explosive properties present in the molecule. Potential explosive properties are indicated by the presence of certain reactive groups in the molecule. The molecular structure of sodium pentaborate indicates that such groups are not present. No reactive or unstable groups are present and it does not contain any functional groups quoted in the "Manual of Tests and Criteria" (fourth revised edition, appendix 6, table A6.1) or in Bretherick's-Handbook (6th Edition, Volume 2) as indicating explosive properties. It can therefore be concluded by expert judgment that the molecular structure does not indicate that this substance will explode under the conditions of the test as described in Test Guideline A.14 of EC Directive 92/69/EEC and therefore testing is not required.
